R help - Jul 2014 - Fwd: Plot the means with simultaneous horizontal and vertical error bars

Dear R users,

I would appreciate your help in plotting the means with simultaneous
horizontal and vertical error bars. I use the lineplot.CI but it creates
the vertical bars only.


The attached file has the dataset that I want to graph. The (X) is the
x-axis values and (y Lint) is the response in y-axis. Therefore, values in
the x-axis would be 150, 350, 550, .....etc.

At each value of the x-axis would be the average response point (y Lint)
with vertical and horizontal error bars.

Each value of the x-axis (X) represents a range of values that in x Water.
The x Water column should be used to draw the horizontal lines.

Thank you so much.

AA
